Simple changes to surgeon preference and creative utilization of instruments can eliminate 40% of costs incurred on robotic instruments alone. Moreover, EBL, operative times, and intraoperative complications are not compromised as a result of cost reduction. Our process of identifying such improvements is straightforward and may be replicated by other robotic surgeons. Further prospective multicenter trials should be initiated to assess other methods of cost reduction.
Numerous treatments have been proposed for Peyronie’s disease (PD). As the evidence base has expanded, the field of operative and non-operative options for patients has narrowed. Collagenase clostridium hystolyticum (CCH) injection now comprises the medical option, and surgical possibilities entail penile plication, plaque incision/excision and grafting, and prosthesis implantation. Still, questions abound regarding the optimal approach and indication for each of these treatments. We conducted a review of literature exploring the contemporary management of PD with a particular focus on work since the last American Urologic Association’s (AUA) guidelines update for PD. Recent results and discussion indicate trends toward minimal invasiveness, toward a more holistic approach to the PD patient, and away from algorithmic management, galvanized, in part, by data challenging long-held beliefs.
Aim We sought to evaluate whether the administration of phenylephrine (PE) at concentrations higher than those described in guidelines resulted in any significant changes in vital signs or impacted outcomes. Methods After receiving institutional review board approval, we retrospectively reviewed the charts of patients presenting to our emergency department between May 1, 2014, and August 15, 2016, using International Classification of Diseases, Ninth Edition and Internation Classification of Disease, Tenth Edition diagnosis codes for priapism. Treatment was reviewed, including corporal aspiration/irrigation, injection of PE, and shunt procedures. Vital signs were compared before and after treatment with PE. Baseline variables were explored with categorical data analysis (chi-squared tests, t-tests, and Mann-Whitney nonparametric tests). Where feasible, linear regression was used to evaluate outcomes. Main Outcome Measure Detumescence and changes in blood pressure and heart rate. Results We identified 74 different patient encounters of acute priapism. The median age was 36.5 years (interquartile range [IQR] = 27–47), and the median time to presentation was 5.4 hours (IQR = 4.0–9.6). 62 percent of cases were due to drug-induced priapism. In 58 (74%) encounters, patients received PE. The median dose of PE given was 1000 μg (IQR 500–2,000). Univariate regression found no association between PE dose and change in patient heart rate or blood pressure. A statistically significant decrease in heart rate (HR) (−4.2 BPM), systolic blood pressure (BP) (−1.8 mm Hg), and diastolic BP (−5.4 mm Hg) was noted. Fifty-three of 58 (91%) patients receiving PE experienced detumescence at the bedside, 2 required shunting in operating room, and 3 refused treatment and left against medical advice. No adverse events occurred. Conclusion We frequently treat patients with high doses of PE and seldom notice adverse effects, typically resulting in resolution of priapism without any additional procedures. Careful administration of high doses of intracavernosal PE in patients presenting with priapism does not appear to significantly affect heart rate or blood pressure and may help prevent further ischemic damage and achieve detumescence effectively and efficiently.
Introduction. Novel disposable products for ureteroscopy are often inherently more expensive than conventional ones. For example, the Cook Flexor© Parallel™ (Flexor) access sheath is designed for ease and efficiency of gaining upper tract access with a solitary wire. We analyze the cost combinations, efficiency, and safety of disposable products utilized for upper tract access, including the Flexor and standard ureteral access sheath. Methods. We performed a retrospective review from January 2014 to October 2014 of patients undergoing URS for nephrolithiasis, who were prestented for various reasons (e.g., infection). Common combinations most utilized at our institution include “Classic,” “Flexor,” and “Standard.” Total costs per technique were calculated. Patient characteristics, operative parameters, and outcomes were compared among the groups. Results. The most commonly used technique involved a standard ureteral sheath and was the most expensive ($294). The second most utilized and least expensive combination involved the Flexor, saving up to $80 per case (27%). All access sheaths were placed successfully and without complications. There were no significant differences in operative time, blood loss, or complications. Conclusions. In prestented patients within this study, the Flexor combination was the most economical. Although the savings appear modest, long-term impact on costs can be substantial.
Surgical site infection rates remain a common postoperative problem that continues to affect patients undergoing urologic surgery. Our study seeks to evaluate the difference in surgical site infection rates in patients undergoing open radical cystectomy when comparing the Bookwalter vs. the Alexis wound retractors. After institutional review board approval, we performed a retrospective chart review from February 2010 through August 2017 of patients undergoing open radical cystectomy with urinary diversion for bladder cancer. We then stratified the groups according to whether or not the surgery was performed with the Alexis or standard Bookwalter retractor. Baseline characteristics and operative outcomes were then compared between the two groups, with the main measure being incidence of surgical site infection as defined by the CDC. We evaluated those presenting with surgical site infections within or greater than 30 postoperatively. Of 237 patients who underwent radical cystectomy with either the Alexis or Bookwalter retractor, 168 patients were eligible to be included in our analysis. There was no statistical difference noted regarding surgical site infections (SSIs) between the two groups; however, the trend was in favor of the Alexis (3%) vs. the Bookwalter (11%) at less than 30 days surgery. The Alexis wound retractor likely poses an advantage in reducing the incidence in surgical site infections in patients undergoing radical cystectomy; however, multicenter studies with larger sample sizes are suggested for further elucidation.
Purpose: most robot-assisted laparoscopic prostatectomies (RALP) are performed with the patient in lithotomy, carrying risks of positioning-related complications. Newer robot models have allowed for supine positioning, potentially avoiding these pitfalls. We gauged the current sentiment on patient positioning among surgeons who perform robot-assisted surgery. Methods: we surveyed members of the Endourological Society regarding their practice settings and their opinions on positioning for robot-assisted laparoscopic prostatectomy. Summary statistics were reviewed and data were analyzed using chi-square tests and t-tests. Results: our survey had 92 eligible respondents. The majority were fellowship-trained, with 51% trained in robotics and 57% practicing in the U.S. with a mean of 13 years of practice. Most were working in an academic setting (69%) and performing at least 25 robotic prostatectomies yearly. 28 respondents used the Intuitive Surgical Inc. da Vinci® Xi™ exclusively (30%), and nearly two-thirds used it sometimes. Although 54% of respondents considered using supine positioning, less than half of these surgeons used it regularly, while 75% overall preferred lithotomy. A majority attributed this choice to surgical team familiarity with lithotomy positioning. Surgeons in the U.S. and those using the da Vinci® Xi™ were more likely to consider supine positioning. Conclusions: lithotomy position is the standard for RALP procedures; nonetheless, it poses significant risks that might be avoided with supine positioning. Our survey suggests that, although supine positioning has been considered, it has not gained momentum in practice. Addressing factors of inertia in training practices and one’s surgical team might allow for novel and safer approaches.
